GLASS-BEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 359,439, dated Marchl5, 1887.

Application filed April 1, 1886. Serial No. 197,382. (No model.)

To afZZ whom it may concern:

Be it known that I, THoMAs F. GILRoY, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inGlass-Beveling Machines, of which the following` is a specification.

The object of my invention is to provide a new and improved machine forbeveling the edges of circular .or oval glass plates, which machine issimple in construction, operates rapidly and accurately, and is providedwith adjustable stops for preventing grinding too much from the edges ofthe glass.

The invention consists in the construction Y and combination of partsand details, as will be fully described and set forth hereinafter, andthen pointed out in the claims.

In the accompanying drawings, forming a part of this specication, and inwhich like letters of reference indicate like parts, Figure 1 1s a sideView of my improved glass-bevelin g machine. Fig. 2 is a plan view ofthe same. Fig. 3 is an end View of the same. parts being shown insection on the line w m, Fig. l. Fig. 4 1s a plan view of the under sideof the arm on which the gage is held, parts being in section on the liney y, Fig. 1. Fig. 5 is a detail cross-sectional view of the swingingframe on the line :c x, Fig. 2. Fig. 6 is a detail View showing thedevice for reciprocating the screw.

rIhe abradingdisk A is mounted on the shaft A', journaled in the frameB, said shaft carrying the belt-pulley A2. The frame B is provided atone end with the arms B', on which the horizontal track-bars B2 areformed, and on said track-bars the carriage C is mounted to slide towardand from the end of the frame B, which carriage is provided with the lugC' on the under side, the said lug forming a nut through which the screwD is passed, which screw is provided at its outer end with thehand-wheel D', and has its inner end swiveled in the end of the link d,which has its other end pivoted on the block d', which is heldadjustably in the transverse groove cl2 of the disk or wheel a, mountedrigidly on the end 'of the shaft b, journaled in brackets Von the end ofthe frame B, and which is rotated by mechanism that will be describedhereina ter. Y

The carriage C is provided with the upwardly-projecting jaws or lugs G2,in which the transverse shaft Eis held, and on the ends of said shaft,which ends project beyond the sides of said lugs or jaws, the Shanks Fof the U-shaped frame F are mounted to swing.

`On the shaft E the united bevel cog-wheel E' and E2 are looselymounted, the wheel E' engaging the bevel cog-wheel G, resting on thefork G', mounted to rock on the shaft E, said 'cog-wheel G beingrevolved by the shaft H, which passes loosely through it, and is provided with a longitudinal spline, I-I',by which it revolves thecog-wheel G. The lower end of the shaft H is passed through the neck orcollar H2 on the fork H", mounted to rock on the shaft I, journaled inbrackets on the end of the frame B and below the shaft b, said shaft Icarrying the bevel cog-wheel I', engaged with the bevel cog-wheel H4 onthelower end of the shaft H.

On one end of the 'shaft I the worm-wheel J is mounted, and engages theworm J' on the end of the shaft J2, journaled in brackets on the nearside of the frame B, which shaft J2 is provided with the belt-pulley J3.On the other end of thek shaft I the bevel cog-wheel g is rigidlymounted, and with it the bevel cog-wheel g engages, which is mountedrigidly on the lower end of the upright shaft h, journaled on the frameB, and on the upper end ofthe shaft h the bevel cog-wheel 7c is rigidlymounted, and engages with the bevel cogwheel m on the end of the shaftb.

The frame F,which is mounted to swing on the shaft E of the carriage C,is provided with the two arms K and L, the former being provided at itsupper end with the two lugs or projections K' and K2. In the upper arm,K, the shaft M is mounted to revolve, and is provided at the lower endwith. the bevel cogwheel M', engaged with the bevel cog-wheel E2 on theshaft E, and on the upper end of the shaft M the bevel cog-wheel M2 ismounted, which is engaged with the bevel cog-wheel N, resting on the top.of the lower lug, K2, of the arm K, and through which bevel cog-wheel Nthe shaft O passes loosely, said shaft passing through the lugs K andK2, and being provided with the spline or feather O', which is passedthrough a groove in the side yof the ap- ICC erture in the cog-wheel N.The upper part of the shaft O is passed through an arm, P, fixed onascrew, Pgpassed through a threaded aperture in the `upper lug, K', andhaving a hand-wheel, R, on its upper end. The upper end of the shaft Ocan turn in the arm P, but cannot move lengthwise through the same,thuscompelling the shaft O to move up and down with lthe screw R and its armP. On the lower end of the shaft O the disk S is mounted rigidly belowthe lower lug, K. On the upper surface of the lower arm, L, of the frameF the disk T is mounted to revolve'at the outer end of said arm L.

On the under side ofthe upper arm, K, the track-bar U is provided, andon the same the stop U is held adjustable by means of a screw. On thetrack-bar U the V-shaped gage U2 is mounted to slide.

The lower arm, L, of the frame F is provided with thelaterally-projecting lugs V on the side edges, and through said lugs thescrews V2 are screwed, thelower ends of which can rest on the carriageC.

' On one shank of the forked end of the frame F the lug a is formed, inwhich the springbolt o is held, the inner end of which can snap into theaperture p in thc side of the carriage C, for the purpose of holding theframe F in place when the same is raised.

An arm, W, projects from the lower part of the frame F, and from saidarm the rod WV extends downward, the lower vend of which passes throughthe aperture NVZ in the upper end of the weight W3, and within a recess,W4, in the weight, into which recess the lower end of the rod Wpasses. Anut, VS7-5, is screwed on said rod, or the rod may be provided with atransverse pin. l

The operation is as follows: The glass r, which is to have its edgesbeveled, is placed on the disk T on the lower arm, L, and then thehand-wheel R is turned, whereby the shaft O is moved downward and thedisk S is pressed upon the glass on the disk T. As the shaft O isrevolved by the gearing previously described the disk S is revolved withit, and with the disk S the glass and the disk T, on which it rests, arealso revolved. During the time the glass is being adjusted in -positionin the manner described the entire frame F is swung up, and is held inthe raised position by the latch-bolt o. TheframeFisthenswungdown, sothat the edgeof the glass r rests upon the edge of the abradingdisk A.The screws V2 are so adjusted as to support the frame F at the desiredinclination and to prevent the frame Fmoving downward too far. In casethe glass r is circular the carriage need not move during the time theedge of the glass is being ground; but when the glass r is elliptical oris oval the carriage must be moved alternately from and toward the edgeof the abrading-disk. When the minor axis of the ellipse is at rightangles to the axis of the abrading-disk, the carriage must be nearestthe edge of the abradingdisk, and when the major axis of the ellipse isat v right angles to the abrading-disk the carriage must be farthestfrom the edge of the abradingdisk. As the disk a revolves the screw D isreciprocated, and thus the carriage is reciprocated, for the purpose setforth above. The stroke of the screw during its reciprocations can beadjusted by adj Listing the pin d a greater or less distance from thecenter of the disk a. When the carriage shall not reciprocate-as, forexample, while beveling a circular piece of glass-the pin el is adjustedat the center of the disk a, or the screw disconnected from the link Il.The carriage must be adj usted a greater or less distance from the edgeof the abradingdisk, according to the diameter of the glass to bebeveled, which is accomplished by turning the screw D by means of itshand-wheel D.

lThe carriage can be reciprocated in the manner set forth at thedifferent adjustments of the carriage from the edge of the abradingdisk,according to the size of the glass.y The gage Uis used to adjust theglass concenv trically with the disks S and T. The stop U is adjusted inthe requisite position on the track according to the size of the glass'and the edges of the glass rested against the shanks of the gage, andthe center of the glass will then be directly over the center of thedisk T.

Itis evident that for larger plates of glass the stop must be adjustedgreater distances from the end ofy the track than for smallerplates--that is, plates having less diameter. The glass plates can beadjusted and locked in place very easily and rapidly, and are beveled ina short time. Y

In my improved machine an abrading-disk having a narrow edge can beused, and the said abrading-disk is worn off on the edge only and not onthe sides or faces. The screws V2 prevent the disk from grinding theedges of the glass disk after the desired bevel has been Vob'- tained.

Vhen the frame F is swung up, the weight I IO WW rests on the floor, anddoes not act on the frame F. When the frame F is swung down, the nut orpin on the lower end of the rod W', within the recess of the weight,strikes the top of the recess ofthe weight, and the weight is thusraised and counterbalances the frame F, thus preventing the edges of aglass (such as watch glass) from being broken or chipped through toomuch weight.

I claim as new and desire to secure by Letters Patentl. A glass bevelingmachine constructed with a sliding carriage, a pivoted frame on saidcarriage, revolving glass-clamping devices on said pivoted frame,gearing for revolving said clamping devices, and a sliding gage on thepivoted frame, substantially as herein shown and described.
